An employment contract in Portugal is more than the page you sign. The Labour Code (Código do Trabalho) sets minimum rights that a contract normally cannot simply remove. Before accepting a job, identify who the employer is, whether the job is permanent or temporary, what you will actually be paid, where and when you work, the probation period, and which collective agreement applies.

The main contract types

  • Contrato sem termo — open-ended/permanent employment, with no predetermined end date.
  • Contrato a termo certo — fixed-term employment with a stated end date and a legally valid temporary reason.
  • Contrato a termo incerto — temporary employment whose exact end date is not known in advance, for example while a particular temporary need continues.
  • Part-time — fewer hours than a comparable full-time worker; special written requirements apply.
  • Trabalho temporário — employment through a licensed temporary-work company, usually to work for a client/user company.
  • Teletrabalho — remote-work arrangements have their own written rules.

Does every employment contract have to be written?

No. Article 110 of the Labour Code says an employment contract generally does not depend on a special form unless the law says otherwise. That means an employee does not automatically lose employment rights merely because the employer failed to hand over a traditional signed contract. However, important arrangements—including fixed-term, part-time, temporary-work and telework contracts—have specific formal/written requirements. In practice, insist on written documentation because proving salary, hours, duties and promises is much easier when they are recorded.

Information the employer must give you

The Labour Code requires extensive information about the employment relationship. This includes the employer, workplace, job/category, start date, any term, holiday entitlement, termination/notice rules, pay and payment method, daily/weekly working time, overtime/shift arrangements, workplace-accident insurance, applicable collective agreement, probation period, training rights and social-protection arrangements. Read the documents before starting and save your own copy.

Fixed-term contracts need a real reason

A fixed-term contract is not simply a permanent job to which an employer has chosen to attach an expiry date. Portuguese law limits term contracts to permitted situations and requires the written contract to identify the term/duration and the facts justifying it. The reason should connect the employer’s temporary need to the proposed term. Under the current Labour Code, a fixed-term contract is generally limited to two years; an uncertain-term contract generally cannot exceed four years. Fixed-term renewal is also restricted. If the legal/formal requirements are not met, the consequences can include treatment as an open-ended employment relationship, depending on the circumstances.

Probation / período experimental

The probation period is the initial period during which both sides assess whether the employment should continue. Current statutory baselines include 90 days for most open-ended employees, potentially 180 days for specified technical/high-responsibility/trust roles and certain first-job/long-term-unemployed situations, and 240 days for management/senior posts. For fixed-term contracts it is generally 30 days where the contract lasts at least six months and 15 days for shorter fixed terms or uncertain terms expected to last no more than six months. Prior work, temporary work, services or internships for the same activity can reduce or eliminate probation in circumstances set out by law. A collective agreement or written agreement can also affect it. Check Article 112 rather than relying on a generic number.

Salary: make the numbers explicit

  • Ask for the gross base salary, not only an estimated net figure.
  • Check how holiday and Christmas subsidies are paid and whether the offer is being described over 12 or 14 payments.
  • Identify meal allowance, commissions, bonuses, shift/night supplements and other benefits separately.
  • Check the pay date and payment method.
  • Do not let a discretionary bonus be presented as guaranteed base salary.

Hours, workplace and duties

Make sure the contract/information matches the job you discussed: function/category, normal daily and weekly hours, shift pattern, workplace, travel expectations and any remote/hybrid arrangement. A vague promise such as “mostly remote” is much harder to rely on than an agreed written telework arrangement. Guide #42 covers working time, holidays and public holidays.

Collective agreements can matter

Your contract is not necessarily the whole rulebook. A collective labour instrument (instrumento de regulamentação coletiva de trabalho) can affect salary scales, categories, allowances, working schedules and other conditions. The employer’s information duties include identifying the applicable instrument where there is one. If something in your contract looks worse than the applicable law or collective agreement, do not assume the signed clause automatically wins.

NISS and foreign workers

A foreign worker does not have to be trapped in the circular argument “no NISS without work, no work without NISS”. As explained in guide #37, current Portuguese government guidance confirms that an employer can sign an employment contract before the worker has a NISS; after the number is issued, the employment relationship is communicated to Social Security. Immigration/right-to-work requirements remain a separate question, so having a contract does not by itself create permission to work where immigration permission is required.

Employment or recibos verdes?

Some genuinely independent professionals work for companies and issue recibos verdes. The problem is a falso recibo verde: someone is labelled an independent contractor while the reality looks like subordinate employment. Article 12 of the Labour Code contains a presumption of employment when characteristics such as working at a place determined by the beneficiary, using its equipment, following set start/end times, receiving a regular fixed payment or performing management/supervisory functions are present in the statutory combination. If the company controls how, where and when you work like an employee, get advice before accepting “freelancer” status merely because it saves the company payroll obligations.

Red flags before signing

  • The employer refuses to identify the legal company/entity.
  • The salary discussed verbally is different from the written base salary.
  • A fixed-term contract gives no meaningful temporary justification.
  • You are told to sign blank pages or documents you cannot keep.
  • Important promises—remote work, commissions, accommodation, vehicle, schedule—are deliberately kept out of writing.
  • You are told you are “self-employed” although the company will control your normal workplace, hours and work like an employee.
  • The employer asks you to return part of your salary in cash.
  • You are charged money merely to receive an ordinary employment contract.

Before you sign: practical checklist

  1. Verify the employer’s legal identity.
  2. Confirm the contract type and, for a term contract, the reason and end/duration.
  3. Check job title/category and actual duties.
  4. Check gross base salary and every allowance/bonus separately.
  5. Check hours, shifts, workplace and remote-work terms.
  6. Check probation and start date.
  7. Ask which collective agreement applies.
  8. Check holiday/Christmas subsidy treatment and workplace-accident insurance.
  9. Resolve verbal promises in writing.
  10. Keep a complete signed copy and subsequent amendments.

If the contract looks wrong

First ask the employer to correct or clarify the document in writing. For labour-law information or suspected violations, contact the Autoridade para as Condições do Trabalho (ACT). The gov.pt Working in Portugal guide is also a useful official starting point. If the dispute could cost you substantial salary, employment status or your job, consider a union or Portuguese employment lawyer rather than relying only on an online explanation.
